idk if this is grooming or not

Hi i’m f17 and today my schools IT guy brought up sex. he’s around 40 or so. i visit him during school hours around 2-5 times a month to say hello and give horror recommendations. today, i visited him and he asked for some recommendations so i gave him some. we’ve known each other since i was a freshman, im a senior now. We have never talked about the romance genre ever. so while i was giving recommendations he told me he had a book recommendation for me called Night Shift by Annie Crown. i saw the cover and i was already suspicious of it since ive read plenty of SMUT. he doesn’t know that. i just told him i read romance novels. he was like yeah the author she’s really good. and he looks at me and asks, “ are the SCENES always so detailed” and i was like what? and scenes meaning sex scenes in books where they are really detailed with cumming and penetration. and i look at the door that was open, and he was like is it okay if i talk about this with you? and i was really uncomfortable and didn’t know what to do so i said “sure i guess” and he didn’t go into detail or anything. i was alone with him. and then he moved onto my tongue piercing and insisted on me sticking my tongue out to show him. i don’t know what this is. we’ve never talked about this before. i think maybe he was dipping a toe in the water to get a feel of how i’d react to it. i already reported it.
